Algae & Zooplankton. Rotifers are an important part of the freshwater zooplankton, being a major food source. Many aquatic organism exhibit diurnal rhythms in their activities, although factors such as light, temperature, food, sex and size have been attributed as probable causes for such behavior of planktonic organisms. Chloride can be toxic, and water quality guidelines have been created to regulate it and protect aquatic life. ... Silver carp and bighead carp are filter feeders, eating phytoplankton and zooplankton respectively. Zooplankton plays an important role in aquatic ecosystem. Daphnia belongs to the suborder Cladocera, which are small crustaceans that are almost exclusively living in freshwater. Algal species succession can also be alteredby intensive, selective (usually size specific) grazing andconcommitant regeneration ofnutrients.

Freshwater zooplankton plays an important role in ponds, lakes and reservoirs An artificial freshwater for the culture of zooplankton was developed. Culture methods Batch culture: At the exponential growth phase of algae, they are inoculated with the freshwater rotifer, B. calyciflorus. Over time as your culture ages, the zooplankton population can reach a point where they are eating the phytoplankton faster than they can reproduce. This publication will concentrate on the culture and feeding of rotifers, but will include information on less used zooplankton such as cladocerans (water fleas), copepods and tintinnid ciliates.
